Hermes Agent is an AI assistant that learns from its use by creating and improving skills, retaining knowledge, searching past conversations, and adapting to its users. It is for people who want to run an agent through a terminal or messaging platforms while connecting it to different AI models and scheduled tasks.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00019 | $0.02954 |
| Opus 5 | $0.00010 | $0.01477 |
| Sonnet 5 | $0.00004 | $0.00591 |
| Haiku 4.5 | $0.00002 | $0.00295 |
Grade A, and why
node-inspect-debugger scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Node.js Inspect Debugger
Overview
When console.log isn't enough, drive Node's built-in V8 inspector programmatically from the terminal. You get real breakpoints, step in/over/out, call-stack walking, local/closure scope dumps, and arbitrary expression evaluation in the paused frame.
Two tools, pick one:
node inspect— built-in, zero install, CLI REPL. Best for quick poking.ndb/ CDP viachrome-remote-interface— scriptable from Node/Python; best when you want to automate many breakpoints, collect state across runs, or debug non-interactively from an agent loop.
Prefer node inspect first. It's always available and the REPL is fast.
When to Use
- A Node test fails and you need to see intermediate state
- ui-tui crashes or behaves wrong and you want to inspect React/Ink state pre-render
- tui_gateway child processes (
_SlashWorker, PTY bridge workers) misbehave - You need to inspect a value in a closure that
console.logcan't reach without patching - Perf: attach to a running process to capture a CPU profile or heap snapshot
Don't use for: things console.log solves in under a minute. Breakpoint-driven debugging is heavier; use it when the payoff is real.
Quick Reference: node inspect REPL
Launch paused on first line:
node inspect path/to/script.js
# or with tsx
node --inspect-brk $(which tsx) path/to/script.ts
The debug> prompt accepts:
| Command | Action |
|---|---|
c or cont |
continue |
n or next |
step over |
s or step |
step into |
o or out |
step out |
pause |
pause running code |
sb('file.js', 42) |
set breakpoint at file.js line 42 |
sb(42) |
set breakpoint at line 42 of current file |
sb('functionName') |
break when function is called |
cb('file.js', 42) |
clear breakpoint |
breakpoints |
list all breakpoints |
bt |
backtrace (call stack) |
list(5) |
show 5 lines of source around current position |
watch('expr') |
evaluate expr on every pause |
watchers |
show watched expressions |
repl |
drop into REPL in current scope (Ctrl+C to exit REPL) |
exec expr |
evaluate expression once |
restart |
restart script |
kill |
kill the script |
.exit |
quit debugger |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

node-inspect-debugger is a skill published in the GitHub repository NousResearch/hermes-agent (242,093 stars, last pushed today), licensed MIT. It adds 19 tokens to every session and 2,954 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
agent-introspection-debugging
Structured self-debugging workflow for AI agent failures using capture, diagnosis, contained recovery, and introspection reports. Use when an agent run fails and you need a reproducible diagnosis instead of a retry.
mem0-status
Diagnoses mem0 connectivity, API key validity, and memory read/write functionality. Use when memory operations fail, searches return empty, addmemory errors occur, or to verify the plugin is working correctly.
debug
Enable debug logging for this session and help diagnose issues.
caveman-explore
Read-only repository explorer for cold-start orientation, broad cross-file localization, or when a direct search failed. Skip it when the exact file or symbol is already named. Returns path:line citations only; its reads stay out of main context.
investigate-first
Diagnose ambiguous failures before editing. Use for unknown causes, intermittent behavior, performance regressions, or investigations needing evidence-ranked hypotheses.
surgical-patch
Fix bugs and small behavior changes at the narrowest responsible layer. Use when regression proof, preserved surrounding behavior, and task-relevant tests matter.
